我使用带有xmlbeans绑定的axis2 wsdl2java工具来生成soap调用的客户端代码。我在OSGi中运行这个客户端，据我所知，我拥有在OSGi中运行axis2所需的所有必要包。每当我尝试使用[class] .Factory.newInstance（）方法创建一个生成的类的实例时，我会收到以下错误：
java.lang.ClassCastException: org.apache.xmlbeans.impl.values.XmlComplexContentImpl cannot be cast to tews6.wsdl.ViewUserSearchTaskContextDocument

我在网上广泛浏览过，发现这个问题的信息很少。任何帮助是极大的赞赏。
